Spring ACL with UUID

Attempt 1

1. Change acl_object_identity.object_id_identity field to varchar.
2. Start application. Expecting error.
3. App started normally (before any page call)
4. Browse page, error come up. (Yes~!)
5. java.lang.String cannot be cast to java.math.BigInteger
6. Error at existing ACL entry.

Attempt 2

1. Try insert an object with UUID as PK.
2. And this is what I'm waiting for: java.lang.NumberFormatException: For input string: "741d25fe-f281-4747-95ef-229c1ba60000"

Attempt 3

1. Create a Java Project in eclipse
2. Import from spring-security-acl-3.0.5.RELEASE-sources.jar
3. Modify (trial-and-error) BasicLookupStrategy.java and ObjectIdentityImpl.java (mostly change long to String)
4. And it works, for now...

Swing Component Data Binding

I wrote a simple class to bind value change of a component to my bean. Someone must have done it many x 10000... times before. :p
Hope it helps.
Require: common-beanutils

package com.dummy;

import java.lang.reflect.InvocationTargetException;

import javax.swing.JSpinner;
import javax.swing.event.CaretEvent;
import javax.swing.event.CaretListener;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;
import javax.swing.text.JTextComponent;

import org.apache.commons.beanutils.BeanUtils;

public class BeanBinder {

 public static void bind(final JSpinner jSpinner, final Object object,
   final String attribute) {
  jSpinner.addChangeListener(new ChangeListener() {

   @Override
   public void stateChanged(ChangeEvent arg0) {
    try {
     BeanUtils.setProperty(object, attribute,
       jSpinner.getValue());
     System.out.println(object);
    } catch (IllegalAccessException e) {
     e.printStackTrace();
    } catch (InvocationTargetException e) {
     e.printStackTrace();
    }
   }
  });
 }

 public static void bind(final JTextComponent textComponent,
   final Object object, final String attribute) {
  textComponent.addCaretListener(new CaretListener() {

   @Override
   public void caretUpdate(CaretEvent arg0) {
    try {
     BeanUtils.setProperty(object, attribute,
       textComponent.getText());
     System.out.println(object);
    } catch (IllegalAccessException e1) {
     e1.printStackTrace();
    } catch (InvocationTargetException e1) {
     e1.printStackTrace();
    }
   }
  });
 }

}
